First off, let's notice that the angle is in the IV Quadrant, where sine is negative and the cosine is positive, likewise the opposite and adjacent angles respectively.
Also let's bear in mind that the hypotenuse is never negative, since it's simply just a radius unit.

Answer
the down payment is $75,750
Explanation
The selling price of a house = $505, 000
The person made a 15% down payment
Down payment = 15% x $505, 000
Down payment = 0.15 x $505, 000
Down payment = $75, 750
Therefore, the down payment is $75,750
